and for sulfur, found as:
\r\n\r\n \tRule 2: The oxidation number of a monatomic (one-atom) ion is the same as the charge on the ion, for example:
\r\n\r\nRule 3: The sum of all oxidation numbers in a neutral compound is zero. Translate the changed phrase: verba bona (acer). A net ionic charge can be specified at the end of the compound between { and }. Multiply the number of moles given by the atoms. A substance is reduced if theres a decrease in its oxidation number. What is the oxidation number of Cu in [CuCl2 (CH3NH2) 2]? The oxidation number of Cu in CuCl is +1. Here, Bu indicates an n-butyl group. Identify the oxidation states of each element in the following formulas. In general, you can say that a substance is oxidized when theres an increase in its oxidation number.\r\n\r\nReduction works the same way. Homework: Oxidation numbers problems. A substance is reduced if theres a decrease in its oxidation number. The oxidation number of metallic copper is zero.
